I ride a rather tall motorcycle and I find that headlights from on coming cars very often blinds me despite the fact that they only have their low beams on. Plus, when riding off road, I find that I either have to keep the visor down and get too hot, or leave it open and get dirt in my eyes. So I'm thinking of buying a pair of polarised Fuglies. Fuglies are heavy duty safety sunglasses that you can buy from here: http://myworld.ebay.com.au/uvwraps/?_trksid=p4340.l2559 This is the pair that I want: http://www.ebay.com.au/itm/Fuglies-...=AU_Fishing_Clothing&var=&hash=item7914a078ec I'm assuming that the Strength option is the amount of tint that they have. Are there any safety concerns when riding with polarised sunglasses or should it be fine? Obviously I'm only going to get a pair with a light tint because I ride at night. Hmm, polychromatic bifocal polarised heavy duty safety sunglasses - now that would be something.
